"The impressive part of this deal is he was able to rapid-fire through in a short period of time and then finished strong at the end," Kocurek told the Dallas Morning News. "Impressive workout."

Kocurek also told the Morning News he was impressed by Brown's game film.

"He put together a really consistent year this year from start to finish," Kocurek said. "That's what you like to see when you're evaluating. You like to see the consistency week after week. He put together a really consistent year. You can tell he's a hard worker."

Brown is a former national top-10 recruit who blossomed into one of the nation's top defensive tackles in 2014 under new Texas coach Charlie Strong. Brown, who is married and has two children, left Texas after his junior season.
